Rock and Roll - Uplifting or Crap

I know this guy and for the sake of anonymity in rock and roll, we will call him Bob (no offense to anyone named Bob). He is disabled and lives a very simple life in a residential care facility. All he does is listen to old rock and roll. He is about fifty years old. I don't know if the rock and roll helps him or hinders him. I know its his outlet but too much of one thing isnt good for anyone. I don't mean too much rock and roll, I mean too much noise always going on. There is something to be said for a good piece of peace and quiet. What do you think?
